periphery thereof. The outer end of this plug is secured to a stem 5, which is slidably mounted in a sleeve 6, formed upon the nozzle and parallel with the outlet portion of said i nozzle. The end of the stem is screw-threaded and projects through a coiled spring 7, while a nut 8 is screwed upon the stem, and by adjusting the same the tension of the spring may be regulated. A lever .9 is fulcrumed upon an ear 10, extending from the nozzle, and one end of this lever is adapted to To all whom it may concern.-

Be it known that I, ISAAC W. HOOVER, a citizen of the United States, residing at Avery, in the county of Erie and State of Ohio, have invented a new and useful Nozzle, of which the following is a specification.

This invention relates to hydrocarbonburners, and more particularly to nozzles such as ordinarily interposed between. the vaporizer and the burner. As is well known to persons acquainted with this art, the vaporization of hydrocarbon oils results in the bear upon the end of the stem 5. formation of carbonaceous particles, which As will be obvious, the spring 7 serves to in practice often clog the outlet-openings of i hold the plug 3 normally seated, so that the the nozzles and oftentimes prevent the opervapor discharged into the nozzle can only esation of the'nozzle. cape through the outlet end by the grooves 4.

The object of the present invention is to Should carbonaceous particles accumulate overcome this objectionable result by prowithin these grooves, and thereby clog them viding a nozzle having means whereby acand retard the escape of the vapor, it is cumulations of particles of this nature may merely necessary to pull on the free end of be quickly blown from the nozzle whenever the lever 9, so as to press the stem 5 longitudesired. dinally. This will result in the compression The invention consists of providing a plug of the spring '7 and the partial withdrawal of in the outlet end of the nozzle, said plug bethe plug from its seat. The vapor will thereing provided in its periphery with grooves, fore blow outward from the nozzle around which when the plug is seated constitute outthe plug and will clean the grooves of any lets through which the vapor is adapted to be material which may have accumulated withdischarged. A spring is provided for holdin them. The plug can be promptly reseating the plug normally seated; but any suit ed by releasing the lever and permitting the able means may be employed. for unseating spring to return it to its normal position. It the plug, and thereby increasing the size of is of course to be understood that any other the discharge-openings and permitting the means than the lever 9 may be employed for gas or vapor under pressure to blow out any actuating the stem and plug. If desired,

this lever may be dispensed with and the spring 7 so tensioned that the increased pressure caused by the clogging of the outlet will be sufficient to overcome the tension of the spring and press the plug outward until the accumulations have been blown therefrom.

The preferred form of the invention has been set forth in the foregoing description; 7 but I do not limit myself thereto, as I am view of the nozzle. Fig. 2 is a section. thereaware that modifications may be made therethrough, showing by dotted lines the plug inl in without departing from the spirit or sacriserted; and Fig. 3 is a detail view of the plug, ficing the advantages thereof, and I therefore its connection with the stem being shown by reserve the right to make such changes as dotted lines. I fairly fall within the scope of the claims.

Referring to the figures by characters of J l/Vhat is claimed is reference, 1 is an angular tube constituting l In a nozzle the combination with a tube the nozzle, one end thereof being adapted to having an oil-passage therethrough, and an be connected to a vaporizer, (not shown,) imperforate sleeve integral with the tube and while the other end is adapted to direct vaparallel with a portion of said passage; of a por into a burner. The outlet end of this I plug movably mounted within the outlet end tube is enlarged interiorly, as shown at 2, to of the tube and having a groove normally form a seat for a frusto-conical plug 3, havconstituting the outlet from the tube, a stem ing a series of grooves 4 formed within the slidably mounted within the imperforate the apertures.

The invention also consists of certain other novel features of construction and combination of parts, which will be hereinafter more fullydescribed, and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.
